Abstract
As shown diagrammatically in Figure 1, fungal plant pathogens may enter susceptible plant tissues directly through epidermal cells (Fig. 1b, h, g), between the anticlinal walls of such cells (Fig. le), through stomata (Fig. 1c, d) or other natural openings, or via wounds (Fig. la) [1]. In most cases, such infections originate from spores on or near the plant surface, and the germ tube commonly differentiates to form a swollen appressorium from which the infection peg develops that enters the plant. Most pathogens show a preference in their mode of penetration, and for those that do not enter through wounds, cytological studies usually suggest that the fungus adheres tightly to the plant surface prior to entry regardless of whether an appressorium develops. For some rust fungi, such adhesion has been shown to be mandatory for the induction of appressoria [2].
